A parallel algorithm for the stable matching problem is presented. The algo
rithm is based on the primal-dual interior path-following method for linear
programming. The main result is that st stable matching can be found in O*
(root m) time by a polynomial number of processors, where m is the total le
ngth of preference lists of individuals. (C) 2000 Published by Elsevier Sci
